I had COVID back in May 2021 and was in quarantine. Things were normal until late August when I started having a cold and got treated with antibiotics. After finishing the antibiotics, I noticed this slight pain on the left side of my chest while breathing deeply, as well as pain in my left hand. It's not sharp anymore, just a constant feeling. My chest X-ray came back normal, but the ECG showed Sinus Tachycardia, and sometimes my heart rate spikes. I'm 26, recently quit smoking, and I'm worried if this could be something like COPD or lung cancer. I can hold my breath for over a minute and can exhale in about 15 seconds, so I'm not breathless. But I'm really anxious, my hands and feet get sweaty, and there's this skin issue on my lower foot which makes me think about hyperthyroidism. Could you help me understand what's going on? I'm seriously worried.

I'm a bit worried because my triglycerides are really high, like 603. I'm curious if taking stanlip 145mg or maybe statins would help bring those numbers down? What's usually recommended to lower triglycerides effectively?

I'm really worried about my mom's situation. She's dealing with restrictive cardiomyopathy, tricuspid regurgitation, and pulmonary hypertension. The doctor suggested she takes sildenafil 20 and Isolazine 20 three times daily, but I've read that mixing these meds can sometimes lead to serious issues. Could this combo be risky for her? She's also on seloken XL 25, Tide 10, and Dabigatran 110. Any advice would really help.
